Description
Technical field
The present invention relates to centrifugal blood technical fields, and in particular to a kind of hospital laboratory double mode blood centrifugal machine.
Background technique
Blood is flowed in the red opaque thick liquid of one of the blood vessel of people and heart.Blood is by blood plasma and blood
Cell composition, contains 900-910 grams of water, 65-85 grams of protein and 20 grams of lower-molecular substance in one liter of blood plasma, and low point
There are many electrolyte and organic compounds in sub- substance, and haemocyte includes red blood cell and leucocyte and blood platelet three classes cell.It is red
Cell average life span is 120 days, and the leucocyte service life is 9-13 days, and platelet life span is 8-9 days.Under normal circumstances, everyone is every
It has the haemocyte aging death of 40ml.Meanwhile also there is the cell neogenesis of respective numbers.
The function of blood includes haemocyte function and blood plasma function two parts, has transport, adjusts human body temperature, defence, tune
Save four functions of human body osmotic pressure and acid-base balance.Red blood cell major function is to transport oxygen to transport carbon dioxide, leucocyte
Major function is to kill bacterium, resists inflammation, participates in vivo immunization generating process, and blood platelet mainly plays hemostasis function in vivo
Can, blood plasma function is mainly nutrition, transports lipid, and buffering forms osmotic pressure, and participation is immune, participates in blood coagulation and anticoagulant functions.
Clinically, blood testing is a kind of common detection means, mainly for the purpose of clinical assistant diagnosis, it is also possible to
Match in physical examination, antenatal identification, immunologic test, the detection of special bone marrow cell, blood donor's screening, bracket for blood grouping with intersecting
Blood test etc..
When using blood testing items physical signs, needing first will be at blood layering using blood centrifugal machine for clinical laboratory
Then reason uses required blood constituent.Blood of human body is known as whole blood after anticoagulation, is broadly divided into three after whole blood centrifugation
Layer, is followed successively by plasma layer, tunica albuginea layer and red blood cell layer from top to bottom.Plasma layer mainly include blood plasma, water, protein, salt and
Various ions etc.；Tunica albuginea floor mainly include rich in blood platelet area, rich in lymphocyte area, rich in monocyte area and rich in grain it is thin
Born of the same parents area, these tangible cell specific gravity are close, therefore are gathered in tunica albuginea layer；Red blood cell layer can simply be divided into Young erythrocyte and normal
Red blood cell, since the two is in the different growing stage of red blood cell, specific gravity slightly has difference.It is layered after being centrifuged according to whole blood
Blood constituent different in each layer can be separated, be prepared into component blood, thus can rationally utilize blood resource by principle,
Meet the needs of patient is to heterogeneity blood, improves therapeutic effect.
But existing more commonly used blood centrifugal machine, mostly uses greatly circular tray designs, and the test tube circle distribution equipped with blood exists
On disk, disk is then driven by servo motor, so that test tube be driven to move in a circle, generates centrifugal force, but this centrifugation masterpiece
With the center of circle is also directed towards, centrifugal effect can have room for promotion.
